no. 1 Embodiment approach

[0042] The first embodiment related to the present invention corresponds to the configuration 1, and constitutes the anti-fog mirror 1, such as figure 1 As shown, the anti-fog mirror 1 has a substrate 5, a metal reflective film 6 and a composite functional layer 7, the metallic reflective film 6 is arranged on the surface of the substrate 5, the composite functional layer 7 is arranged on the metallic reflective film 6, and It has photocatalytic function and hydrophilic function. And, the film thickness of the composite functional layer 7 is set so that L * a * b * a of the chromaticity diagram of the color system * value and b * The values ​​are 25 to -25 (preferably 20 to -20), respectively. Alternatively, the film thickness of the composite functional layer 7 is set to make L * a * b * The chromaticity c represented by the above formula (1) in the chromaticity diagram of the color system * The value is 35 or less (preferably 30 or less).

no. 2 Embodiment approach

[0056] The second embodiment of the present invention corresponds to the configuration 3, and constitutes the anti-fog mirror 2, such as figure 2 The anti-fog mirror 2 shown has a substrate 5, a metal reflective film 6 and a composite functional layer 7, the metallic reflective film 6 is arranged on the surface of the substrate 5, and the composite functional layer 7 is arranged on the metallic reflective film 6, by sequentially The photocatalytic functional layer 8 and the hydrophilic functional layer 9 are formed. And, the film thickness of the composite functional layer 7 is set so that L * a * b * a of the chromaticity diagram of the color system * value and b * Values ​​are 25~-25 (or chroma c * value is less than or equal to 35), it is preferable to make a * value and b * Values ​​are 20~-20 (or chroma c * value is less than or equal to 30).

[0057] In addition, the present inventors investigated the parameters affecting the spectral reflectance of the reflect...

no. 3 Embodiment approach

[0064] The third embodiment of the present invention corresponds to configuration 4, and constitutes an anti-fog mirror 3, such as image 3 The anti-fog mirror 3 shown has a base material 5, a metal reflective film 6, a reflectance adjustment layer 10 and a composite functional layer 7, the metal reflective film 6 is arranged on the base material 5, and the reflectance adjustment layer 10 is arranged on the metal reflector The film 6 is composed of a substance with a refractive index lower than that of the composite functional layer 7 (photocatalyst substance). The composite functional layer 7 is arranged on the reflectivity adjustment layer 10 and has both photocatalytic function and hydrophilic function ( For example by TiO alone 2 Composite functional layer 7). And, the film thickness of the composite functional layer 7 is set so that L * a * b * a of the chromaticity diagram of the color system * value and b * Values ​​are 25~-25 (or chroma c * value is less than or...

Abstract

The object of the present invention is to provide an anti-fog mirror whose reflective color is a neutral tone (the a* value and b* value of the chromaticity diagram of the L*a*b* color system are in a colorless tone region). The anti-fog mirror 1 of the present invention has the following structure, and it has a metal reflective film 6 and a composite functional layer 7 on the surface of the substrate 5 from the substrate 5 side, and the composite functional layer 7 includes a photocatalyst material layer 8 and a hydrophilic function layer. Layer 9, the film thickness of the composite functional layer 7 is set so that the a* value and b* value of the chromaticity diagram of the L*a*b* color system are 20-20 respectively.

Description

technical field [0001] The invention relates to an anti-fog mirror, in particular to an anti-fog mirror whose reflection color is neutral. Background technique [0002] The so-called anti-fog mirror is a reflective mirror that has the property of removing water droplets adhering to the surface of the mirror. Conventional anti-fog mirrors are broadly classified into the following cases: the surface of the mirror is subjected to a hydrophobic treatment to increase the hydrophobicity of water, so that the attached water droplets are formed into beads and removed; properties, so that the attached water droplets are expanded into a thin film and removed. For the above-mentioned anti-fog mirror with hydrophobic treatment on the surface of the mirror, the water attached to the surface is in the shape of beads (hemispherical with small curvature) water droplets. The bright image is reflected by the lower half of the water droplet to increase the visibility. [0003] Therefore, re...
